Actuator with mechanical lock

Actuator with adjustable stroke

Mechanical locking

All actuators are delivered with Mechanical Locking as standard. The mechanism is integrated in the actuator and totally independent of hydraulic oil. If there is loss of hydraulic pressure or even a fire, the valve will be kept safe in last position (open/close).

Easy maintenance

The Mechanical Locking gives the feature of Easy Maintenance as well. The only regular maintenance we recommend on Scana Skarpenord actuators, is changing of the piston sealing. Because of the Mechanical Locking, the sealing can be replaced without any dismantling. The actuator can remain attached to the valve and the valve does not have to be disconnected from the pipeline. The maintenance can be performed with the valve safe locked in fully closed or open position. Full flow can be maintained in the pipeline during maintenance.

EAL™ Hydraulic Oil

Our VRC systems is also suited for use with EAL™ Hydraulic Oil and can be used upon customers preference. This is premium quality, high performance hydraulic oils developed to meet the demand for environmentally acceptable hydraulic fluids
